' and removing the snow produced by operation .of the machine on theiceblocks; to provide means for preventing operation of'the machine when noice block is in position for scoring; to provide means for automaticallyenclosing the scoring devices so as to render the machine safe when itisnot in use; and to provide a single set of scoring devices for scoringon more than one side of the ice block.

Numerous other objects and the advantages of my improved machine willappear fr-om the following description, reference being made to theaccompanying drawings in which p r Fig. 1 1s a plan view of my lmprovedmachine.

Fig. 2 is a side elevation.

Fig. 3 is a top plan view of the machine with the top plate removed.

Fig. 4 is a front elevation of the machine.

Fig. 5 is a cross sectional view of the ma chine approximatelv on theline 55 of Fig. 2 with an ice block therein which has been scored on oneside and whichis being scored on another side.

Fig. 6 is a vertical sectional view approximately on the line 6-6 ofFig. 1.

In the embodiment of the invention shown any improved machine comprisesa base 1 havin'gan outlet 2 for discharging into a drain pipe 3 the snowproduced by operation of the scoring devices on the ice blocks. Twoupright angle bars & are rigidlysecured to opposite sides of the baseand each has on its lower end a curved extension 5 (Fig. .2). The .ex-

tensions 5curve around the edge of the base to abutting contact with anupright channel bar 6. The channel bar 6 is secured in-upright positionby rigid supporting elements 7 ('Fig. 6) and the angle bars taresecureolin upright position by attachment to projections 8 form- 55 ingrigid guide chutes ,9. These guidechutes 9 are connected by an outwardlycurved strap or bar 10 andby an inwardly curved strap or bar 11. Thechutes 9 are therefore rigid with each otherand rigid with the frame ofthe machine comprising the base 1 andthe bars 4. The upper ends of thebars 4 are connectedby an angle bar 12 having'a notch 13".

The top plate 13 of the machine is rigidly attached to the upper ends ofthe bars 4 and 6 and to the bar 12 and projects forwardly beyond thebars 4. An electric motor 14 is removably attached to the top plate 13by removable fasteners 15 and is controlled by a switch 16 mounted onthe top plat-e13 in convenient position for operation by the person incharge of the machine. The motor shaft 17 is connected to the upper endof a vertical shaft 18 by an insulation coupling 19. The lower end ofthe shaft 18 is mounted in a hearing 20 supported by the bar 11. Theshaft 18 supports a seriesof scoring devices comprising circular saWsQlmounted on the shaft in spaced relationship and projecting forwardlybeyond the plane of the bar 11.

Arturntable 22'operates upon a bearing 23 on the forward extension ofthe base land has along its outer edge a flange 24 and along its inneredge a guide flange 25. An upright channel bar 26 has its lower endattached to the turntable 22 and supports a number of spaced supportingarms27 against which the blocks of ice are held when the machine isoperating. The upper end of the bar 26 supports a bracket 28 to which isrigidly secured an internal gear 29. The gear 29 has an axle 3Q journaled in a bearing 31 attached to the top plate13. The axle is inaxial alinement with the bearing 23 so that the frame comprising'theseparts is rotative. An ice block holder comprising a bail 31 has itsendspivoted to the bracket 28 and is movable to and from position to embracethe upper endof an ice block mounted on the turntable 22 as will bereadily understood by reference to Fig. 6. 1 0

An angular latch spring 32 is attached to the front end of the bail 31and is movable into and out of latching engagement with the top plate13, said plate being formed with a notch 33 in its forward edge toreceive said latch spring. When the latch spring 32 is in latchingengagement with the top plate 13 the bail 31 is supported thereby in theposition indicated by broken lines in Fig. 6 so as to permit movement ofan ice block onto or from the turntable 22. A handle 34 is attached tothe front end of the bail 31 for manipulating the same.

A hand wheel 35 is attached to the upper end of a shaft 36 journaled forrotation in a bearing 37 rigid on the top plate 13. The lower end of theshaft 36 has rigid thereon a pinion 38 meshing with the internal gear 29so that said gear 29 and thereby the turntable 22 may be rotated by saidwheel 35.

- The side flanges 24 and 25 of the turntable 22 are arranged so thatwhen the machine is idle said fianges are in alinement with the chutes 9to permit movement of an ice block through either of said chutes ontothe turntable and subsequent removal of the scored ice block from themachine. The turntable is normally held in this position by a lever 39mounted on a pivot 40 in connection with the top plate 13 and having atooth 41 designed and arranged to engage in a notch in the periphery ofthe internal gear 29 (Fig. 3). The lever 39 is actuated to this latchingengagement by a longitudinally movable stem '42 having one end abuttingagainst an arm 43 on said lever 39 and the'opposite end in connectionwith a slidable valve device 44 in a water pipe 45. A spring 46 ismounted on the stem 42 having one end abutting against the valve support44 and the opposite end against a collar 47 on said stem. Thusthespring/16 is utilized to actuate the lever 39 to an extent to latch saidlever with the gear wheel 29 and is also utilized tomove the valve stem42 in a direction and to an extent to close the valve in the pipe 45.Thus when the turntable is latchedin starting position the valve 44 isclosed. And when the machine is in use and the turntable is beingrotated the lever 39 is held in position in which the valve verticaledge hinged to the bar 6 by hinges 50 (Fig. 3). and the other edgeprovided with a pivoted latch element 51 movable into and out ofengagement with arkeeper 52 on the adjacent bar 4. Thesewalls '49 are,therefore, capable of being swung from and to closed positions and whenopen afi'ord access to the inside'of the machine. When closed the walls49 confine the show so that the 'snow will be forced down to and throughthe outlet 2 and the drain pipe 3.

WVhen the machine is to be used the turntable 22 is adjusted so that ablock of ice may pass thereto from either of the chutes 9. The block ofice is then moved onto the turntable and the bail 31 is lowered from thebroken line position to the solid line position, as shown in Fig. 6, soas to hold the block of ice against the supporting arms 27. The motorbeing started, the scoring saws 21 are rapidly rotated. The latch lever39 is then released from latching engagement with the gear wheel 29which opens the valve 44 and causes a flow of water through the nozzle48 suflicient to wash the snow through the outlet 2 into the drain pipe3. The hand wheel 35 is then rotated which rotates the support or frameon which the block of ice is mounted, bringing opposite edges of theblock of ice successively into contact with the scorers 21 so thatparallel kerfs or scores are formed in opposite sides of the block ofice, as will be understood by reference to Fig. 5. The rotative frame onwhich the ice is mounted is stopped in its initial or starting positionautomatically because when the notch in the wheel 29 is brought oppositethe tooth 41 the spring 46 acts to move the lever 39 in a direction andto an extent to engage the tooth 41 in the notch in said wheel 29. Thenthe bail 31 is raised to latching engagement with the top plate 13 so asto permit the scored block of ice to be moved from'the machine. Therotative ice block supporting frame cannot be latched in any other thanits proper position to receive a block of ice.

If the spring 33 of the bail 31 becomes unlatched or disconnected fromthe plate 13 when there is no block of ice on the turntable 22 one orboth of the extreme inner ends 31 of the bail 31 will engage in thenotch or notches 13 and thus positively prevent the turntable 22 frombeing turned bythe wheel 35 or otherwise. Accordingly, this arrangementacts as a safety device to prevent operation of the turntable when themachine is empty.

From the foregoing it is apparent that my invention obtains all of itsintended objects and purposes in a highly satisfactory and efliclentmanner; that the operative mechanism is covered and enclosed in order toprevent accidents; that the snow produced by the scoring devices istrapped by the machine and is flushed from the machine automatically andas an incident to the operation of the machine; that the rotary iceblock supporting frame is stopped automatically in position to receiveand to discharge the blocks of ice; that the machine is compact and maybe mounted in a comparatively small space; that the machine includes aminimum number of parts and may be manufactured and sold at low cost;and possessesmany other advantages made apparent by the foregoingdescriptlon.
